Process Water Purification

The treatment to reuse the water used in the production process

Process waters refer to the streams used in production activities, which are loaded with chemicals, both organic and inorganic, in the operational stages.

To contain the water supply from outside, they can be treated and stripped of excess elements, achieving the degree of purity suitable for reuse in the processing cycle.

Coind Wastewater

Purification of primary water occurs through chemical, physical, or process water purification occurs through chemical or physical reactions, which include separation from:

  1. Dissolved salts
  2. Nitrogen, nitrate and phosphorus
  3. Bacterial load
  4. Chlorides, sulfates
  5. Oils and minerals
  6. Any metals such as iron, copper, zinc, chromium

Plants of
Process Water Purification

Water Softening

Adaptation of the liquid to the production line, preventing carbonates in the water from settling and reducing the passage sections.

Activated Carbon Adsorption

Removal of organic molecules by passing water or air over a bed of granular activated carbon. The operation can be manual or automated with pneumatic valves.

Water Decanter

Separation of coarse molecules that allow for the reduction of machinery space and exponentially increase water quality.

Demineralization to Ion Exchange Resins

Separation of dissolved salts, either for the supply water of a production process or, in the case of recirculating systems, for the recovery of water directly in production.

Sea Water Desalinators

Use of reverse osmosis membranes to enable the achievement of high quality in water treatment. Possibility of potabilization of sea water or adaptation for industrial processes.

Electrocomposting Animal Droppings

Treatment of animal manure by electrolysis and electrocoagulation to obtain soil suitable for the parameters required for use in agriculture.

Water Nanofiltration

Flow filtration with appropriate membranes, capable of removing nanometer-sized particles.

Industrial Reverse Osmosis

Production of demineralized water through semipermeable membranes on pressurization systems. When installed downstream of purification systems, it allows wastewater recovery, with the possibility of using the flow again in productions.

Water Cooling

Temperature regulation of water flows. It is applied with heat exchangers or specific unit heaters.

Recovery in Water Production

Use of specific facilities to recover water flows directly into productions.

Sludge treatment

Separation of sludge by settling systems and subsequent thickening before dewatering through a filter press in a sludge warehouse.

Ultrafiltration Water

High-level filtration by displacement of fluid over membranes. It is used for primary water purification or to separate molecules.
